The New China. By Henri Borel. New 



York: Dodd, Mead & Company: 1912. 



Cloth. 8vo. Gilt top. Illustrated. 273 



pages. Price, $3.50 net. 



Henri Borel, author of "The New 

 China," says in his introduction to this 

 work (translated from the Dutch by C. 

 Thieme), the awakening of China to a 

 national consc : ousness is a process sud- 

 denly excited by the thunder of Japanese 

 guns after a long period of silent brood- 

 ing, and it is beyond the pale possibility to 

 estimate the immense influence it may have 

 on the evolut'on of the whole world in the 

 domain of politics, economics, science and 

 art. 



This timely book has been written by one 

 who combines an unusual aptitude for close 

 observation with unusual facilities for mak- 

 ing observations in his chosen field. As a 

 consequence of his official position in the 

 Dutch East-Indies, it was natural that his 

 interest should extend from the Chinese in 

 the Dutch Colonies to the Chinese in China. 

 And as a result of extended visits and much 

 travel he has written a book in which he 

 brings before the reader what is now going 

 on in the oldest and most populous of all 

 nations — a i evolution so subtle, so swift, so 

 complete, and so tremendous in its far- 

 reaching influences upon the whole world 

 that no event within the memory of any 

 now living can equal it in importance. 



The Boy Electricians as Detectives. By 



Edwin J. Houston. Philadelphia : J. B. 



Lippincott Company: 1912. Cloth. 8vo. 



Illustrated. 341 pages. Price, $1.25 net. 



Th's is a sequel to Dr. Houston's "The 

 Boy Electrician, a book for boys that suc- 

 ceeded admirably in blending entertain- 

 ment with instruction, and one is pleased 

 to note that in "The Boy Electricians as 

 Detectives," the author has given the juve- 

 nile world a book bound to awaken a scien- 

 tific interest in the young reader. Wireless 

 telegraphy plays a prominent part in the 

 plot of the story. 



The Boy's Playbook of Science. By 

 John Henry Pepper. Revised by Tohn 

 Mastin, M. A., D.Sc, Ph.D. New York: 

 E. P. Dutton & Co.: 1912. 8vo. 680 

 pages. Illustrated. Price, $2.50 net. 

 Years ago. when our old boys were 

 young, the popularized science of John 

 Henry Pepper furnished them with many 

 an hour of recreation and instruction. 

 Now one of his books, "The Boy's Play- 

 book of Science," comes to us with a fan- 

 fare of trumpets as "revised, rewritten, and 

 re-illustrated, with many additions." A 

 perusal of the reviser's preface leads one 

 to expect great things, but on close ex- 

 amination it is found that the new edition 

 is nothing short of an imposition upon an 

 unsuspecting public. There are a few pic- 

 tures of aeroplanes and a page or two of 

 futile description ; two pages of drawings 

 of the modern locomotive; brief mention 

 of radio-activity and wireless telegraphy; 

 and some poor illustrations of the turbine. 

 These seem, to be the additions most promi- 

 nent. The preface epitomizes the faults 

 of the volume. It consists of unfulfilled 

 promise, perfervid exhortation to the youth
